Revealing divergent length scales using quantum Fisher information in the Kitaev honeycomb model
James Lambert, Erik S. Sørensen
We compute the quantum Fisher information (QFI) associated with two different local operators in the Kitaev honeycomb model, and find divergent behaviour in the second derivatives…
The Heart of Entanglement: Chiral, Nematic, and Incommensurate Phases in the Kitaev-Gamma Ladder in a Field
Erik S. Sørensen, Andrei Catuneanu, Jacob Gordon +1
The bond-dependent Kitaev model on the honeycomb lattice with anyonic excitations has recently attracted considerable attention. However, in solid state materials other spin intera…
Classical spin order near antiferromagnetic Kitaev point in the spin-1/2 Kitaev-Gamma chain
Wang Yang, Alberto Nocera, Erik S. Sørensen +2
A minimal Kitaev-Gamma model has been recently investigated to understand various Kitaev systems. In the one-dimensional Kitaev-Gamma chain, an emergent SU(2) phase and a rank-…
